Sedentary Behavior and Ultra-Processed Food Consumption Associated to BMI Changes in Brazilian Students During COVID-19.

INTRODUCTION: University students experienced significant changes in their routines with the implementation of remote learning during Covid-19 pandemic, including increase in sedentary behavior (SB) time and ultra-processed foods (UPF's) consumption, which may have influenced changes in body mass index (BMI). OBJECTIVE: To evaluate the association between the variation in SB time and UPF's consumption with the variation in BMI, before and during the pandemic, in university students. METHODS: This is a cross-sectional study, conducted between November 2020 and February 2021, with students from a public university of Southeast of Brazil, who answered an online questionnaire with questions regarding to the period before and during the pandemic. SB was assessed through questions about time spent on TV and electronic devices. A score of the frequency of UPF's consumption was estimated based on the Brazilian Food Guide. Self-reported information on height and body mass was used to calculate BMI. RESULTS: The sample comprised 3390 university students, with an average age of 28.7 (± 10.0) years. Among them, 65.4% were undergraduates, and 66.9% were women. SB time, UPF score, and BMI increased significantly during the pandemic, compared to the previous period. In this population, there was a significant association between increased SB time (ß = 0.06; SE = 0.01; p < 0.001) and UPF score (ß = 0.08; SE = 0.01; p < 0.001) with an increase in BMI. CONCLUSION: Changes in SB time and UPF score were associated with an increase in BMI before and during the COVID-19 pandemic in students from a Brazilian University.

Tropical fruits as a potential source for the recovery of bioactive compounds: Tamarindus indica L., Annona muricata, Psidium guajava and Mangifera indica.

The objective of this review is to identify the bioactive compounds present in tropical fruits such as Tamarindus indica L., Annona muricata, Mangifera indica, and Psidium guajava and their biological activities. The identification of these compounds shows their potential as a food ingredient in the development of products, providing added value to them, because not only the pulp of the fruit is used, but also the shell and its other parts, such as the leaves, are used, being viable sources to obtain some compounds that benefit human health. Implementing fruits that have certain bioactive compounds such as carotenoids (ß-carotene, α-carotene, lutein, zeaxanthin and ß-cryptoxanthin), antioxidants (vitamins A and C), and phenolic compounds (ellagic acid, gallic acid, citric acid) in the production process in the food industry, allows them to become functional foodstuffs. The results obtained show the need to implement the operational processes that allow obtaining different compounds, which ensure their stability and precision, applying different extraction methods such as maceration, Soxhlet, supercritical fluids, and ultrasound.

Adherence to the EAT-Lancet sustainable diet and ultra-processed food consumption: findings from a nationwide population-based study in Brazil.

OBJECTIVE: To evaluate the association between ultra-processed food consumption and adherence to the EAT-Lancet diet in a representative sample of the Brazilian population. DESIGN: The study used data from the Brazilian National Dietary Survey 2017-2018 and employed linear regression models to evaluate the association between ultra-processed food consumption and adherence to the EAT-Lancet diet, as measured by the Nova food system and Planetary Health Diet Index (PHDI), respectively. SETTING: Nationally representative sample of the Brazilian population. PARTICIPANTS: The study included 46 164 Brazilians ≥ 10 years old. RESULTS: The average PHDI total score was 45·9 points (95 % CI 45·6, 46·1). The ultra-processed food consumption was, with dose-response, inversely associated with the adherence to the EAT-Lancet diet. The PHDI total score was 5·38 points lower (95 % CI -6·01, -4·75) in individuals in the highest quintile of consumption of ultra-processed foods, as compared to those in the first quintile. The PHDI score was also inversely associated with the share of processed culinary ingredients and processed foods and positively associated with the share of unprocessed or minimally processed foods. CONCLUSIONS: Our study showed an inverse relationship between the consumption of ultra-processed foods and the adherence to a healthy and sustainable diet.

"Warning: ultra-processed": an online experiment examining the impact of ultra-processed warning labels on consumers' product perceptions and behavioral intentions.

BACKGROUND: Nutrient content and degree of processing are complementary but distinct concepts, and a growing body of evidence shows that ultra-processed foods (UPFs) can have detrimental health effects independently from nutrient content. 10 + countries currently mandate front-of-package labels (FOPL) to inform consumers when products are high in added sugars, saturated fat, and/or sodium. Public health advocates have been calling for the addition of ultra-processed warning labels to these FOPLs, but the extent to which consumers would understand and be influenced by such labels remains unknown. We examined whether the addition of ultra-processed warning labels to existing nutrient warning labels could influence consumers' product perceptions and purchase intentions. METHODS: In 2023, a sample of adults in Brazil (n = 1,004) answered an open-ended question about the meaning of the term "ultra-processed," followed by an online experiment where they saw four ultra-processed products carrying warning labels. Participants were randomly assigned to view either only nutrient warning labels or nutrient plus ultra-processed warning labels. Participants then answered questions about their intentions to purchase the products, product perceptions, and perceived label effectiveness. RESULTS: Most participants (69%) exhibited a moderate understanding of the term "ultra-processed" prior to the experiment. The addition of an ultra-processed warning label led to a higher share of participants who correctly identified the products as UPFs compared to nutrient warning labels alone (Cohen's d = 0.16, p = 0.02). However, the addition of the ultra-processed warning label did not significantly influence purchase intentions, product healthfulness perceptions, or perceived label effectiveness compared to nutrient warning labels alone (all p > 0.05). In exploratory analyses, demographic characteristics and prior understanding of the concept of UPF did not moderate the effect of ultra-processed warning labels. CONCLUSIONS: Ultra-processed warning labels may help consumers better identify UPFs, although they do not seem to influence behavioral intentions and product perceptions beyond the influence already exerted by nutrient warning labels. Future research should examine how ultra-processed warning labels would work for products that do and do not require nutrient warnings, as well as examine the benefits of labeling approaches that signal the health effects of UPFs.

The EAT-Lancet diet associated cardiovascular health parameters: evidence from a Brazilian study.

BACKGROUND: The EAT-Lancet diet is a diet aimed at promoting population and planetary health from the perspective of sustainable diets in terms of environmental and health aspects. This study aimed to assess the association between adherence to the EAT-Lancet diet and cardiometabolic risk factors among adults and elderly individuals in a capital city in the northeastern region of Brazil. METHODS: This is an analytical cross-sectional observational study from a population-based sample conducted between 2019 and 2020, involving 398 non-institutionalized adults and elderly people, of both sexes from "Brazilian Usual Consumption Assessment" study (Brazuca-Natal). There was a 38% response rate due to the suspension of data collection due to the covid-19 pandemic, but According to the comparative analysis of socioeconomic and demographic variables between the surveyed and non-surveyed sectors, losses were found to be random (p = 0.135, Little's MCAR test). Socioeconomic and lifestyle data, anthropometric measurements, and dietary consumption were collected. We used the Planetary Health Diet Index (PHDI) and the Cardiovascular Health Diet Index (CHDI) for cardiovascular health to assess adherence to the diet's sustainability. The evaluated cardiometabolic parameters included fasting blood glucose, triglycerides, total cholesterol, HDL-C, LDL-C, and systolic and diastolic blood pressure measurements. We also assessed the presence of type 2 diabetes mellitus, arterial hypertension, and dyslipidemia. For the data analyses, sample weights and the effect of the study design were taken into account. Pearson's chi-square test was used to evaluate the statistical significance of frequencies. Multiple linear regression models assessed the associations between PHDI and CHDI and its components and the cardiometabolic parameters. RESULTS: The mean PHDI was 29.4 (95% CI 28.04:30.81), on a total score ranging from 0 to 150 points and the mean CHDI was 32.63 (95% CI 31.50:33.78), on a total score ranging from 0 to 110 points. PHDI showed a significant positive association with the final CHDI score and components of fruits, vegetables, and legumes, and a negative association with Ultra-processed Food (UPF) (p < 0.05). Notably, among the most consumed UPF, the following stand out: "packaged snacks, shoestring potatoes, and crackers" (16.94%), followed by margarine (14.14%). The PHDI exhibited a significant association with diabetes and dyslipidemia, as well as with systolic blood pressure, total cholesterol, and LDL-C. CONCLUSIONS: The results suggest that adopting the EAT-Lancet diet is associated with the improvement of key cardiovascular health indicators.

Monitoring sodium content in processed and ultraprocessed foods in Argentina 2022: compliance with National Legislation and Regional Targets.

OBJECTIVE: To assess the current Na levels in a variety of processed food groups and categories available in the Argentinean market to monitor compliance with the National Law and to compare the current Na content levels with the updated Pan American Health Organisation (PAHO) regional targets. DESIGN: Observational cross-sectional study. SETTING AND PARTICIPANTS: Argentina. Data were collected during March 2022 in the city of Buenos Aires in two of the main supermarket chains. We carried out a systematic survey of pre-packaged food products available in the food supply assessing Na content as reported in nutrition information panels. RESULTS: We surveyed 3997 food products, and the Na content of 760 and 2511 of them was compared with the maximum levels according to the Argentinean law and the regional targets, respectively. All food categories presented high variability of Na content. More than 90 % of the products included in the National Sodium Reduction Law were found to be compliant. Food groups with high median Na, such as meat and fish condiments, leavening flour and appetisers are not included in the National Law. In turn, comparisons with PAHO regional targets indicated that more than 50 % of the products were found to exceed the regional targets for Na. CONCLUSIONS: This evidence suggests that it is imperative to update the National Sodium Reduction Law based on regional public health standards, adding new food groups and setting more stringent legal targets.

Assessment of Vegetable Species for Microgreen Production in Unheated Greenhouses: Yield, Nutritional Composition, and Sensory Perception.

Cultivating microgreens in central-southern Chile in unheated greenhouses offers a viable and productive alternative to growers. In 2023, two experiments were conducted in autumn and spring. These experiments involved the production of microgreens of eleven vegetable species. The tray system with the substrate was employed. Subsequently, agronomic, nutritional, and sensory perception variables were assessed. Despite notable fluctuations in external temperatures between these seasons, a diverse array of microgreens can be successfully cultivated, meeting local consumer preferences. Research indicates that microgreens grown under these conditions exhibit high nutritional quality, serving as a rich source of essential nutrients and bioactive compounds beneficial to human health. This nutritional value remains consistent across autumn and spring, establishing microgreens as a reliable and valuable food option. The observed acceptance and purchasing intentions among the surveyed population suggest a promising market opportunity for introducing these products regionally. Consumers appreciate microgreens' quality and nutritional advantages, underscoring their potential.

The Role of Lactic Acid Bacteria in Meat Products, Not Just as Starter Cultures.

Lactic acid bacteria (LABs) are microorganisms of significant scientific and industrial importance and have great potential for application in meat and meat products. This comprehensive review addresses the main characteristics of LABs, their nutritional, functional, and technological benefits, and especially their importance not only as starter cultures. LABs produce several metabolites during their fermentation process, which include bioactive compounds, such as peptides with antimicrobial, antidiabetic, antihypertensive, and immunomodulatory properties. These metabolites present several benefits as health promoters but are also important from a technological point of view. For example, bacteriocins, organic acids, and other compounds are of great importance, whether from a sensory or product quality or a safety point of view. With the production of GABA, exopolysaccharides, antioxidants, and vitamins are beneficial metabolites that influence safety, technological processes, and even health-promoting consumer benefits. Despite the benefits, this review also highlights that some LABs may present virulence properties, requiring critical evaluation for using specific strains in food formulations. Overall, this review hopes to contribute to the scientific literature by increasing knowledge of the various benefits of LABs in meat and meat products.

Green Tea Kombucha Impacts Inflammation and Salivary Microbiota in Individuals with Excess Body Weight: A Randomized Controlled Trial.

BACKGROUND: Green tea kombucha (GTK) is a fermented beverage with promising health benefits, but few studies proved its impact on human health. Thus, we aimed to investigate the impact of GTK on weight loss, inflammation, and salivary microbiota in individuals with excess body weight. METHODS: This is a randomized controlled clinical trial that lasted 10 weeks with two groups of individuals with excess body weight: control (CG; n = 29; caloric restriction) and kombucha (KG; n = 30; caloric restriction + 200 mL GTK). Body composition, anthropometry, saliva, and blood collection were performed in the beginning and end of the intervention. Plasma interleukins were determined by flow cytometry. Salivary microbiota was analyzed by 16S rRNA sequencing. RESULTS: Both groups decreased weight, BMI, and body fat (p < 0.001) after the intervention, but there were no differences between groups. The KG reduced lipid accumulation product (LAP) (p = 0.029). Both groups decreased IL-1ß and IL-8, but IL-6 increased in the CG (p = 0.023) compared to the kombucha group. Alpha and beta diversity of salivary microbiota increased in the KG. Moreover, the KG presented lower Bacillota/Bacteroidota ratio (p = 0.028), and BMI was positively associated with the Bacillota phylum. CONCLUSIONS: GTK did not enhance weight loss, but it decreased the LAP. GTK helped in the inflammatory profile and induced positive changes in oral microbiota composition.

How can advocates leverage power to advance comprehensive regulation on ultra-processed foods? learning from advocate experience in Argentina.

BACKGROUND: The use of corporate power to undermine public health policy processes is increasingly well understood; however, relatively little scholarship examines how advocates can leverage power to promote the successful adoption of public health policies. The objective of this paper is to explore how advocates leveraged three forms of power - structural, instrumental and discursive - to promote the passage of the Promotion of Healthy Eating Law (Ley 27,642) in Argentina, one of the most comprehensive policies to introduce mandatory front-of-package (FOP) warning labels and regulate the marketing and sales of ultra-processed foods (UPFs) adopted to date. METHODS: We conducted seventeen semi-structured interviews with advocates from different sectors, including civil society, international agencies, and government. Both data collection and analysis were guided by Milsom's conceptual framework for analyzing power in public health policymaking, and the data was analyzed using hybrid deductive and inductive thematic analysis. RESULTS: Advocates harnessed structural power through the leveraging of revolving doors, informal alliances, and formal coalitions, enabling them to convene discussion spaces with decision-makers, make strategic use of limited resources, and cultivate the diverse expertise (e.g., research, nutrition science, advocacy, law, political science, activism and communications) needed to support the law through different phases of the policy process. Advocates wielded instrumental power by amassing an armada of localized evidence to promote robust policy design, building technical literacy amongst themselves and decision-makers, and exposing conflicts of interest to harness public pressure. Advocates exercised discursive power by adopting a rights-based discourse, including of children and adolescents and of consumers to transparent information, which enabled advocates to foster a favorable perception of the law amongst both decision-makers and the public. Key contextual enablers include a political window of opportunity, the COVID-19 pandemic, and the ability to learn from the regional precedent of similar policies. CONCLUSIONS: Public health policymaking, particularly when encroaching upon corporate interests, is characterized by stark imbalances of power that hinder policy decisions. The strategies identified in the case of Argentina provide important insights as to how advocates might harness and exercise structural, instrumental, and discursive power to counter corporate influence and promote the successful adoption of comprehensive UPF regulation.

RESUMEN: ANTECEDENTES: El uso del poder corporativo para socavar los procesos de políticas de salud pública se comprende cada vez mejor; sin embargo, relativamente pocos estudios examinan cómo los defensores pueden aprovechar el poder para promover la adopción exitosa de políticas de salud pública. El objetivo de este artículo es explorar cómo sus defensores aprovecharon tres formas de poder ­ estructural, instrumental y discursivo ­ para promover la aprobación de la Ley de Promoción de la Alimentación Saludable (Ley 27.642) en Argentina -una de las políticas más integrales adoptadas hasta la fecha- que establece la obligatoriedad del etiquetado frontal de advertencias en alimentos y bebidas envasados y regula la comercialización y venta de productos comestibles y bebibles ultraprocesados (PUP). MéTODOS: Realizamos diecisiete entrevistas semiestructuradas con defensores de diferentes sectores, incluyendo sociedad civil, agencias internacionales y gobierno. Tanto la recolección como el análisis de datos se guiaron por el marco conceptual de Milsom para analizar el poder en la formulación de políticas de salud pública, y los datos se analizaron mediante un análisis temático híbrido deductivo e inductivo. RESULTADOS: Los defensores sacaron provecho del poder estructural mediante el uso de puertas giratorias, alianzas informales y coaliciones formales, lo que les permitió generar espacios de discusión con los tomadores de decisiones, hacer uso estratégico de recursos limitados y profundizar la experticia diversa (por ejemplo, en investigación, ciencia de la nutrición, abogacía, derecho, ciencias políticas, activismo y comunicación) necesaria para apoyar la ley a través de las diferentes fases del proceso político. Los defensores ejercieron poder instrumental al acumular abundante evidencia local para promover un diseño de políticas sólidas, construir conocimientos técnicos entre ellos y los tomadores de decisiones, y exponer conflictos de intereses para ejercer presión pública. Los defensores ejercieron poder discursivo al adoptar un discurso con enfoque de derechos -incluyendo el de niños, niñas y adolescentes, y el de los consumidores a acceder a una información transparente-, lo que les permitió fomentar una percepción favorable hacia la ley tanto entre los tomadores de decisiones como entre el público. Los facilitadores contextuales clave incluyen una ventana de oportunidad política, la pandemia de COVID-19 y la capacidad de aprender de la experiencia regional en políticas similares. CONCLUSIONES: La formulación de políticas de salud pública, particularmente cuando menoscaban los intereses corporativos, se caracteriza por marcados desequilibrios de poder que obstaculizan las decisiones políticas. Las estrategias identificadas en el caso de Argentina brindan ideas importantes sobre cómo los defensores podrían aprovechar y ejercer el poder estructural, instrumental y discursivo para contrarrestar la influencia corporativa y promover la adopción exitosa de una regulación integral de PUP.

An internet-based self-help intervention for the reduction of consumption of ultra-processed products and increase of physical activity in Mexican university population: study protocol for a randomized controlled trial.

Introduction: The consumption of ultra-processed products has been associated with the etiology of various diseases, mainly metabolic diseases. On the other hand, physical activity acts as a protective factor that helps prevent the appearance of this type of disease. In addition to the physical effects, both the consumption of ultra-processed products (UPPs) and sedentary behaviors have been associated with a significant impact on people's mental health. These problems occur significantly in university students. Online internet interventions are an alternative that has the advantage of reaching a broader sample size and adapting to various problems. Methods: A randomized controlled clinical superiority trial with two independent groups will be developed with 176 participants. Participants in both groups will be evaluated in 5 steps: (1) pretest, (2) middle of the intervention, (3) post-test, (4) follow-up at 3 months, and (5) follow-up at 6 months. In the experimental group ("UNISALUD"), participants will receive an intervention composed of 11 sessions with interactive elements such as videos, audio, and infographics created through the user experience (UX) principles and based on the health action process approach (HAPA). The participants in the control group will be on the waiting list and will receive treatment 27 days after fulfilling the inclusion criteria. Thus, participants will not receive the treatment immediately. Discussion: The study is expected to establish the feasibility of a self-help internet-based intervention created based on the user experience methodology and the health action process model, leading to a significant decrease and increase in the consumption of UPPs, ultra-healthy products, and physical activity, respectively. Conclusion: Internet-based interventions are scarce in Latin America. Due to their potential, this study will provide data about consumption of UPPs, physical activity, and mental health of the Mexican population, which will influence the reduction of health-related complications through prevention strategies or measures.Clinical Trial Registration:ClinicalTrials.gov, NCT05834842.

The role of culture in the representation of probiotic foods.

Functional foods, and specifically probiotics, are important products present in retail worldwide. Probiotics comprise "live microorganisms that, when administered in adequate amounts, can confer a health benefit on the host". This study aimed to investigate the effect of culture on probiotic foods social representation. A total of 818 consumers from seven countries (Argentina, Brazil, Honduras, Mauritius, Mexico, Peru, and Slovenia) participated in the study. A free word association task was performed with the inductor term "probiotic food," followed by lemmatization, categorization, and prototypical analysis of the social representation. The results indicated that the term health was common in all countries studied, as well as other positive aspects such as benefits, well-being, and functional foods. This study helped to shed light and better understand the role of culture in the social representation of probiotics.

Daily Intake of Household-Produced Milk Kefir on Salmonella Typhimurium Infection in C57BL/6 Mice: Mortality, Microbiota Modulation and Immunological Implications.

AIMS: Salmonellosis, a major global cause of diarrheal diseases, significantly impacts the intestinal microbiome. Probiotic-rich beverages, such as kefir, are increasingly utilized as alternative health-promoting beverages associated with various microbiota benefits. This study investigated the repercussions of daily consumption of household-produced milk kefir on Salmonella enterica serovar Typhimurium infection in C57BL-6 mice. METHODS AND RESULTS: Kefir consumption pre infection reduced the presence of inflammatory cells in the colon and altered the cytokine profile by reducing IL-10 and increasing IFN-γ. Despite reducing intestinal inflammation, kefir intake did not yield a prompt response to an acute infection caused by the aggressive pathogen Salmonella. This contributed to increased mortality in the mice, evidenced by higher fecal Salmonella counts post-infection. Metabarcoding analysis demonstrated that the use of kefir before infection increases butyric acid by the higher abundance of Lachnospiraceae and Prevotellaceae families and genus in feces, coupled with an increase in Muribaculaceae family and Bacteroides genus among infected kefir-treated mice. While kefir hinted at microbiota alterations reducing enterobacteria (Helicobacter), decrease IL-10, and increased IFN-γ, butyric acid on pre-infection, the beverage potentially facilitated the systemic translocation of pathogens, intensifying the infection's severity by altering the immune response. CONCLUSIONS: The use of kefir in the dosage of 10% w/v (109 CFU), for acute infections with Salmonella Typhimurium, may not be enough to combat the infection and worsen the prognosis, leaving the intestine less inflamed, favoring the replication and translocation of the pathogen. These findings underscore the importance of prudently evaluating the widespread use of probiotics and probiotic-rich beverages, especially during acute infections, given their potential association with adverse effects during these diseases.

Development of QSARs for cysteine-containing di- and tripeptides with antioxidant activity:influence of the cysteine position.

Antioxidants agents play an essential role in the food industry for improving the oxidative stability of food products. In the last years, the search for new natural antioxidants has increased due to the potential high toxicity of chemical additives. Therefore, the synthesis and evaluation of the antioxidant activity in peptides is a field of current research. In this study, we performed a Quantitative Structure Activity Relationship analysis (QSAR) of cysteine-containing 19 dipeptides and 19 tripeptides. The main objective is to bring information on the relationship between the structure of peptides and their antioxidant activity. For this purpose, 1D and 2D molecular descriptors were calculated using the PaDEL software, which provides information about the structure, shape, size, charge, polarity, solubility and other aspects of the compounds. Different QSAR model for di- and tripeptides were developed. The statistic parameters for di-peptides model (R2train = 0.947 and R2test = 0.804) and for tripeptide models (R2train = 0.923 and R2test = 0.847) indicate that the generated models have high predictive capacity. Then, the influence of the cysteine position was analyzed predicting the antioxidant activity for new di- and tripeptides, and comparing them with glutathione. In dipeptides, excepting SC, TC and VC, the activity increases when cysteine is at the N-terminal position. For tripeptides, we observed a notable increase in activity when cysteine is placed in the N-terminal position.

Mental health from childhood to adolescence predicts excessive weight and body composition at 18 years.

OBJECTIVE: To investigate the association of mental health in childhood and adolescence with four outcomes at 18 years: ultra-processed food (UPF) consumption, body mass index (BMI), excessive weight (EW), and body composition, including fat mass (FM) and fat free mass (FFM) in kg, FM index (FMI) and FFM index (FFMI) in kg/m2. METHODS: Cohort study in which The Development and Well-Being Assessment (DAWBA) (6 and 11 years) and the MINI International Neuropsychiatric Interview (MINI) (18 years) provided information on internalizing (INT), externalizing (EXT) and any mental disorder (ANY). The exposure was classified in: "never", "at 6 and/or 11 years", "at 18 years only" and "at 6, 11, and 18 years". Linear and logistic regression were run. All analyses were stratified by sex. RESULTS: A total of 2722 participants were analyzed. At 18 years, female with EXT disorders at 6 and/or 11 years presented higher BMI (ß: 1.70; 0.18-3.23), FM (ß: 4.74; 1.42-8.06), and FMI (ß: 1.53; 0.28-2.79) than those who never had. The odds of EW at 18 years was also higher in females with EXT disorders at 6 and/or 11 years (OR: 3.39; 1.56-7.36) and at the three time points (OR: 7.08; 1.69-29.59). Males with EXT disorders at 6 and/or 11 years presented higher FM (ß: 4.45; 1.85-7.06) and FMI (ß: 1.47; 0.63-2.31). CONCLUSIONS: Among children and adolescents showing symptoms of EXT disorders, weight should be monitored carefully, thus ultimately contributing to reduce the burden of EW in adolescence.

Altered Brain Reactivity to Food Cues in Undergraduate Students with Disordered Eating Behaviors.

PURPOSE: A growing body of evidence has shown that electroencephalography (EEG) is an interesting method of assessing the underlying brain physiology associated with disordered eating. Using EEG, we sought to evaluate brain reactivity to hyper-palatable food cues in undergraduate students with disordered eating behavior (DEB). METHODS: After assessing the eating behaviors of twenty-six undergraduate students using the Eating Attitudes Test (EAT-26), electroencephalographic signals were recorded while the participants were presented with pictures of hyper-palatable food. The current study used a temporospatial principal component analysis (PCA) approach to identify event-related potential (ERP) responses that differed between DEB and non-DEB individuals. RESULTS: A temporospatial PCA applied to the ERPs identified a positivity with a maximum amplitude at 347 ms at the occipital-temporal electrodes in response to pictures of hyper-palatable food. This positivity was correlated with the EAT-26 scores. Participants with DEB showed reduced positivities in this component compared with those without DEB. CONCLUSION: Our findings may reflect greater motivated attention toward hyper-palatable food cues in undergraduate students with DEB. These results are an important step toward obtaining a more refined understanding of specific abnormalities related to reactivity to food cues in this population.

The Cashew Pseudofruit (Anacardium occidentale): Composition, Processing Effects on Bioactive Compounds and Potential Benefits for Human Health.

The fruit of the cashew, a tree belonging to the family Anacardiaceae, is composed of approximately 10% nut (cashew) and 90% stalk or pseudofruit, usually discarded in situ and fermented in the soil. This review identifies cashew pseudofruit's physicochemical characteristics and bioactive compounds and their possible relationship to health benefits. Different processing techniques have been used to preserve the pseudofruit, and the effect of these techniques on its nutrients is also reviewed in this work. Cashew is a highly perishable product with moisture content above 80% w/w and 10% w/w sugars. It also has a high content of polyphenols, flavonoids, and tannins and high antioxidant properties that are best preserved by nonthermal processing techniques. The pseudofruit presents the high inhibitory activity of α-amylase and lipase enzymes, has anti-inflammatory and body weight reduction properties and healing activity, and controls glucose levels, insulinemia, and insulin resistance. For all these reasons, cashews have been promoted as a propitious food/ingredient for preventive and therapeutic management of different pathologies such as diabetes, dyslipidemia, obesity, hypertension, fatty liver, and acne. Moreover, it has positive effects on the intestinal microflora, among others. This pseudofruit has a high potential for the development of functional foods.

Cupuaçu (Theobroma grandiflorum): A Multifunctional Amazonian Fruit with Extensive Benefits.

The Amazon region is known for its continental dimension, water abundance, and especially for the rich biodiversity that this biome hosts. Among the thousands of plant species in the Amazon, many represent food sources. Among these, cupuaçu (Theobroma grandiflorum (Willd. ex Spreng.) K.Schum.) stands out as an iconic fruit with an exotic flavor, appreciated for its remarkable organoleptic properties. The present review aims to provide a comprehensive description of its biology, agronomical uses, nutritional values, chemical compositions, medicinal properties, and industrial applications. The search based on scientific articles demonstrates T. grandiflorum as a valuable ingredient for the food, cosmetic and pharmaceutical sectors. Data analysis demonstrates that cupuaçu cultivation and processing contribute to the strengthening of local production chains and promotes the development of small communities, and thus the bioeconomy in the Amazon region. In this sense, since the last decade, cultivar improvement has required multidisciplinary efforts, resulting in disease-resistant plants with better productivity. Regarding its chemical composition, T. grandiflorum is a notable source of methylxanthine alkaloids, polyphenols, aroma compounds, and lipids. The presence of these compounds supports the use of cupuaçu in various products and help us to understand the potential health benefits of its consumption. Through the integration of all collected information, key gaps in basic and applied sciences were observed, highlighting the need for more research to uncover novel applications and products of T. grandiflorum. The development of new products based on biodiversity is fundamental to promoting environmental and economic sustainability, which are key steps to the survival of the Amazon rainforest. Therefore, this work summarizes the knowledge on this source and sheds light on a food source that is little known outside of the Amazon borders.

Pinhão potential and their parts (failures, shells, and almonds) in the elaboration of yogurts containing acai pulp: physicochemical, nutritional, and functional properties, antimicrobial activity, and multi-elemental profile.

This study applies natural resources, prioritizing recyclable and renewable inputs produced by pinhão cultivation, whose purpose is to use the failures, shells, and almonds as a source of bioactive compounds addition in yogurt, ensuring intelligent use of these natural resources. Thus, one açaí yogurt sample and eight yogurt formulations containing portions of pinhão byproducts between 5 % and 10 % were elaborated. These formulations were compared regarding their physicochemical, nutritional, functional properties, antimicrobial activity, and multi-elemental profile properties. Enriching açaí yogurt with pinhão byproducts does not significantly differ in protein, lipid, moisture, and mineral salt content between all samples with pinhão byproducts. Açaí yogurts enriched with pinhão byproducts had 5.71 to 26.07 % times total protein than the control sample, and total fiber also had a significant increase in samples ranging between 18.62 to 85.29 % times more than the control sample. Regarding color settings, all yogurt samples tended to be red-purple. A sample of açaí yogurt with pine nut flour and whole pine nut flour caused a biofilm mass amount of 46.58, 45.55, and 11.85 % for Listeria monocytogenes, Salmonella enteritidis and Pseudomonas aeruginosa. The behavior of pathogenic bacteria is related to the total polyphenol content in yogurts enriched with pinhão byproducts, which increased from 8.27 to 18.24 mg/100 g. Yogurt with açaí enriched with whole pinhão flour showed high antioxidant capacity. The sample's antioxidant activity results increased by 47.62 % and 130.38 % in the ABTS and DPPH analyses, respectively. The compounds in pinhão failure nanosuspensions, pinhão flour, whole pinhão flour, and yogurts were identified and divided into hydrophilic and lipophilic classes. Five classes (amino acids, organic acids, sugars, phenols, and cyclitols) were identified as hydrophilic. Lipophilic compounds were identified and separated into six classes (carboxylic acids, diterpenes, alcohols, Α-hydroxy acids, sterols, and triterpenes). The addition of pinhão byproducts increased the contents of Ca, Fe, K, Na, and P. Açaí yogurt with pinhão nanosuspension, pinhão flour, and whole pinhão flour had the highest Ca content (2164.38 ± 2.16 µg/L). Açaí yogurt with pinhão flour and whole pinhão flour had the highest Fe content (84.02 ± 0.08 µg/L).
